Galectin-3: a novel protein in cerebellar hemangioblastoma.

Hemangioblastoma (HB), a rare neoplasm of uncertain histogenesis, is characterized histologically by the presence of vacuolated; lipid-containing cells 'stromal cells' and a well developed, fine capillary network. Stromal cells are the neoplastic component of this tumor. Five-um sections were stained using streptavidin- biotin immunoperoxidase and immunofluorescent techniques.

Expression of Galectin-3, CD138, p16INK4a, and TTF-1 in mucinous bronchioloalveolar adenocarcinoma after Hodgkin lymphoma.

Bronchioloalveolar carcinoma (BAC) is a subset of lung adenocarcinoma that has a distinct clinical presentation, tumor biology, response to therapy, and prognosis compared with other subtypes of non-small-cell lung carcinoma. BAC disproportionately affects women, never-smokers, and is characterized by growth along alveolar septae without evidence of stromal, vascular, or pleural invasion. Microscopically, BACs have been divided into mucinous, nonmucinous, and mixed types.

Churg-Strauss syndrome presenting as an abdominal mass in a non-asthmatic child.

A 2-year-old boy presented with an abdominal mass and was diagnosed as Churg-Strauss syndrome (CSS). There was no history of asthma. He developed fatal gastro-intestinal disease, despite treatment with corticosteroids and cyclophosphamide.
